Jon Hamm and Jennifer Westfeldt at Jaeger-LeCoultre Watch Event in New York

Jon Hamm Makes Time For 30 Rock Before Mad Men's Finale

Jon Hamm hosted an event for luxury watch company Jaeger-LeCoultre with his girlfriend Jennifer Westfeldt in NYC on Tuesday night. On Sunday night the US will get to see how things end for womanising Don Draper on the Mad Men's season finale, but he'll be on the small screen tonight as one of Liz Lemon's many love interests for the live episode of 30 Rock. The cast and special guests, which also includes Matt Damon as airplane pilot Carol, will perform once for the East Coast and once for the West, both of which will be streaming on NBC.com.
